The Clinical Relevance of Fragile Histidine Triad Protein (FHIT) in Patients with Bladder Cancer.	BACKGROUND The present study aimed to investigate the clinical relevance of fragile histidine triad protein (FHIT) in patients with bladder cancer (BC). MATERIAL AND METHODS Three independent BC microarray studies were collected and reanalyzed. The expression of FHIT was evaluated between BC samples and normal bladder tissues. The correlation between the expression of FHIT and clinicopathological features was analyzed using the chi-square test. Log-rank based survival analysis was conducted to detect the survival significance of FHIT in patients with BC. Gene set enrichment analysis (GSEA) was performed to identify the mechanisms. RESULTS FHIT was significantly downregulated in BC cells (p=0.0044). BC patients in the FHIT high expression group had better clinical characteristics (including invasiveness, tumor grade, disease progression, and T staging) than those in the FHIT low expression group (p<0.0001, p<0.0001, p=0.031, p<0.0001, and p=0.056, respectively). Patients in the FHIT high expression group had better cancer-specific survival (p<0.0001) and overall survival (p=0.0008) than those in the FHIT low expression. GSEA results indicated that BC samples in the FHIT low expression group were enriched in interferon alpha response, apoptosis, androgen response, interferon gamma response, heme metabolism, and transforming growth facto r(TGF) beta signaling. CONCLUSIONS FHIT predicts better clinical relevance for patients with BC, which may be a promising therapeutic target.	bladder
Health-Related Quality of Life, Perceived Social Support, and Depression in Disease-Free Survivors Who Underwent Curative Surgery Only for Prostate, Kidney and Bladder Cancer: Comparison among Survivors and with the General Population.	PURPOSE: The purpose of this study was to compare health-related quality of life (HRQoL) of disease-free prostate (PC), kidney (KC), and bladder cancer (BC) survivors with that of the general population. MATERIALS AND METHODS: Our study included 331 urological cancer (UC) survivors (114 PC, 108 KC, and 109 BC) aged ≥ 50 years disease-free for at least 1 year after surgery. The control group included 1,177 subjects without a history of cancer. The HRQoL was assessed using the European Organization for Research and Treatment of Cancer QLQ-C30, the Duke-UNC Functional Social Support Questionnaire, and the Patient Health Questionnaire-9. RESULTS: There was no significant difference between the groups in terms of any of the functioning sub-scales and symptoms, except significantly lower social functioning observed in BC survivors than that observed in KC survivors. Although the three groups of UC survivors showed essentially similar functioning sub-scales and symptoms when compared to the general population, PC and BC survivors showed significantly lower social functioning and a lower appetite than that observed in controls. KC survivors showed lower physical functioning, as well as higher pain and dyspnea. Although all three groups of UC survivors reported higher financial difficulties, they also reported higher perceived social support than that reported by the non-cancer control group. No statistically significant difference was observed in terms of depressive symptoms between each group of UC survivors and the general population. CONCLUSION: Disease-free survivors of the three major types of UCs showed generally similar HRQoL compared to the general population, as well as compared to each other.	bladder
[Mitomycin C HIVEC. Update and results in high risk patients.].	Adjuvant endovesical treatment is a research field in constant exploration with the aim to minimize the risk of recurrence and progression of non muscle invasive bladder tumors. Over the last years, the administration of chemotherapy in a chemo hyperthermia regimen has been added to the existing regimens. There are various systems for its administration, but this article focus on HIVEC (Hyperthermic IntraVEsical Chemotherapy) and its current status. In this review article we update the results of this system in the case-scenarios it has been used (preoperative with ablative intention and as adjuvant therapy with prophylactic purposes), tolerance and security issues, on-going clinical trials and future perspectives.	bladder
[New endovesical chemotherapy drugs and application vehicles.].	Urothelial bladder cancer is a very prevalent disease. At the time of diagnosis 70-80% of the cases present as non muscle invasive tumors. These tumors present a high recurrence and progression rates despite intravesical treatment with Bacille Calmette-Guerin and mitomycin C. Moreover, bladder conditions such as its wall impermeability and the fact that intravesical drugs are constantly being diluted by urine and eliminated do not favor the efficacy of intravesical treatment. This review analyzes new intravesical drugs such as gemcitabine or taxanes with promising results as alternative to the usual treatments or after their failure. In the same way, we detail those application vehicles designed to increase the exposition of the drug to the bladder wall and its penetration into it. We emphasize drug releasing systems, albumin nanoparticles, liposomes, magnetic nanocarriers, polymers, thermosensible hydrogels and mucoadhesives such as chitosan.	bladder
[BCG and bladder cancer: Past, present and future.].	BCG has been used in the treatment of NMIBC for more than 40 years. Nevertheless, its exact working mechanisms have not been completely discovered. Clinical and basic research done over all these years has generated much information but it could be summarized in a few simple statements. It has been demonstrated the best route of administration is intravesical, BCG is superior than intracavitary chemotherapy to prevent recurrence but its adverse events are worse. Recently, it has been demonstrated that BCG could delay or prevent progression to infiltrative cancer. Nevertheless, to achieve this, maintenance therapy is necessary. Therefore, the recommendation is to treat middle and high risk cases with BCG. No significant differences in efficacy have been found between the various strains but differences in recurrence have been found between standard and reduced doses.Furthermore, the presence or absence of side effects does not seem to be a prognostic factor for the efficacy of BCG and, maintenance therapy is not associated with a significant increase in toxicity. In the future, the optimal schedule and doses must be defined, and it probably will be different for each individual. BCG shortage has led to try alternative therapies through chemo hyperthermia or electrical gradient application the efficacy of which should be evaluated. New strains and immunological treatments are also under research.	bladder
Treatment of Urothelial Cancer in Elderly Patients: Focus on Immune Checkpoint Inhibitors.	Urothelial carcinoma, or bladder cancer, is a malignancy that most commonly affects older patients. The median age at diagnosis is 73 years, and care of these patients requires consideration not just of the disease-related factors such as stage and histology, but also of patient-related factors. Many of these patients have concurrent medical morbidities and additional changes related to the aging process. Older patients with cancer are a unique population requiring additional considerations and assessment in treatment decision-making. It is important to look beyond chronologic age. The traditional treatment for advanced disease has relied on platinum-based chemotherapy. These multi-agent regimens require consideration of baseline organ function as well as competing conditions that may heighten toxicity. The advent of a new class of cancer therapeutics, the immune checkpoint inhibitors, has changed the care of patients with advanced disease considerably. These immunotherapeutics have been approved for treating patients with disease progression on chemotherapy, or those who are ineligible (or unfit) to receive cisplatin-based therapy. This expansion of the population of patients eligible for treatment has great applicability to the unique considerations in an older patient population. In general, these new immunotherapies are well tolerated and effective in this group of patients.	bladder
Utility of intravoxel incoherent motion MRI derived parameters for prediction of aggressiveness in urothelial bladder carcinoma.	BACKGROUND: Preoperative accurate judgment of aggressiveness is of great importance to determine treatment and prognosis of bladder cancers. PURPOSE: To evaluate the utility of IVIM-MRI parameters in predicting aggressiveness of bladder urothelial carcinoma. STUDY TYPE: Prospective. POPULATION MODEL: Sixty-seven patients with bladder urothelial cancer. FIELD STRENGTH/SEQUENCE: 3.0 T/T2WI and IVIM-MRI. ASSESSMENT: All cases were categorized in low-, intermediate-, or high-aggressiveness proposed by Kobayashi depending on the T stage and pathological grade. Images analysis and IVIM-derived parameters (apparent diffusion coefficient standard ADC, true diffusion coefficient D, pseudodiffusion coefficient D*, and perfusion fraction f) measurements were performed independently by two radiologists. STATISTICAL TESTS: Comparisons of IVIM-derived parameters in different aggressiveness levels were performed using one-way analysis of variance or Kruskal-Wallis test. Binary logistic regression models were used to calculate predicted probability of combined parameters. Diagnostic performance of individual and combined parameters for distinguishing high- from low-/intermediate-aggressiveness was assessed by using the receiver operating characteristics (ROC) curve. RESULTS: The ADC and D values differed significantly among low-, intermediate-, and high-aggressive urothelial bladder carcinoma, respectively (P < 0.05). The f value showed significant differences between low- and high-aggressive and between intermediate- and high-aggressive bladder carcinoma (P < 0.05). The best parameter for differentiating high- from low-/intermediate-aggressive urothelial bladder carcinoma was ADC value, with the area under ROC curve (AUC) and accuracy of 0.895 and 85.97%, followed by f and D values with AUCs of 0.873 and 0.862, respectively. The best combination of parameters was combined D and f values, with AUC and accuracy of 0.931 and 91.82%. DATA CONCLUSION: ADC value showed slightly better diagnostic performance than D and f values in predicting bladder cancer aggressiveness. The combination of D and f model can produce a robust value than single parameter in evaluating aggressiveness. LEVEL OF EVIDENCE: 1 Technical Efficacy: Stage 3 J. Magn. Reson.

Risk factors for bladder cancer recurrence survival in patients with upper-tract urothelial carcinoma.	PURPOSE: The aim of this work was to investigate the predictive factors for bladder cancer recurrence survival (BCRS) in patients with upper-tract urothelial carcinoma (UTUC). METHODS: We selected patients with UTUC who underwent segmental ureterectomy (Su) or nephroureterectomy (Nu) from 2004 to 2013 from the Surveillance, Epidemiology, and End Results (SEER) database. Patients with a history of intravesical therapy for bladder cancer and bladder cancer prior to the diagnosis of UTUC were excluded. We used Kaplan-Meier analysis, log-rank tests, and Cox proportional hazards model to compare overall survival, cancer-specific survival, and BCRS. RESULTS: In a cohort of 1,454 patients, 169 (11.6%) had low-grade tumors and 1,285 (88.4%) had high-grade tumors; 239 (16.4%) underwent Su and 1,215 (83.6%) underwent Nu. We found that T4 grade (hazard ratio [HR] = 6.216; 95% confidence interval [CI], 3.197-12.087) and ureteral tumors (HR = 1.764; 95% CI, 1.173-2.652) were predictors of shorter BCRS, whereas Nu (HR = 0.608; 95% CI, 0.388-0.953) predicted longer BCRS. Five-year BCRS rates were low-grade tumors: 94.1%, high-grade tumors: 85.4% (p = 0.038); plus Su: 82.9%, and Nu: 87.6% (p = 0.016). CONCLUSIONS: Use of Su should be more selective for high-grade tumors, as it correlates with shorter BCRS. Tumors located in the ureter are associated with shorter BCRS than those located in the renal pelvis.	bladder
Progressive tissue biomarker profiling in non-muscle-invasive bladder cancer.	The recurrence rate of non-muscle-invasive bladder cancer (NMIBC) is up to 60% within the first year of therapy. Accurate risk stratification is necessary for patient counselling, follow-up scheduling and individualized therapeutic decision making. Current prognostic models rely on clinicopathologic features, but their discrimination remains limited when in external cohorts. Despite intense efforts regarding the value of biomarkers in prognosticating outcomes in NMIBC, clinical utility remains suboptimal. It is clear that a single biomarker is not enough for the prediction of disease recurrence. Therefore, panels of non-redundant biomarkers have been created and integrated in clinical prognostic model further research relying on high throughput technologies is required. Areas covered: We performed a systematic research of the English-language literature on tissue biomarkers for prediction of NMIBC outcomes up to December 2017. Expert commentary: Despite the essential milestones achieved in our knowledge and understanding of the molecular biology underlying NMIBC, no biomarker has been implemented together with clinical feature in clinical practice. Integration of such biomarkers into predictive and prognostic model could, however, improve our accuracy, thereby paving the way for personalized medicine in the management of NMIBC.	bladder
Development of a Cryptosporidium-arsenic multi-risk assessment model for infant formula prepared with tap water in France.	Tap water is used in France to reconstitute powder infant formula, although it is not sterile and possibly contaminated by microbiological and chemical hazards. The present study aims to quantify risks of using tap water in France for the preparation of infant formula, during the first six months of life. Cryptosporidium and arsenic were selected as hazards of greatest concern in microbiology and chemistry, respectively. A probabilistic model was developed using French (when available) and European (alternatively) data. Second order Monte Carlo simulation was used to separate uncertainty and variability of inputs. Outputs were expressed at the individual level as probability of illness and at the population level, using a common metric, the DALY (Disability Adjusted Life Year). Two scenarios of milk preparation were considered: with un-boiled or boiled tap water. Consuming infant formula rehydrated with un-boiled tap water during the first six months of life led to a total of 2250 DALYs per 100,000 infants (90% uncertainty interval [960; 7650]) for Cryptosporidium due to diarrhea, and 1 DALY [0.4; 2] for arsenic due to expected lifetime risk of lung and bladder cancer as a result of early exposure in life. For the entire population, boiling water would suppress the risk from Cryptosporidium. In contrast, the incremental cancer risk was low at the population level but elevated for 5% of the population exposed to high levels of arsenic. A stringent monitoring of tap water supply points should be continued. This multi-risk assessment model could help public health authorities and managers in evaluating both microbiological and chemical safety issues associated with using infant formula prepared with tap water.	bladder
Bacillus Calmette-Guérin may have clinical benefit for glandular or squamous differentiation in non-muscle invasive bladder cancer patients: retrospective multicenter study.	OBJECTIVES: To clarify the efficacy of intravesical Bacillus Calmette-Guérin (BCG) instillation for non-muscle invasive bladder (NMIBC) cancer with variant histology, especially glandular differentiation or squamous differentiation. MATERIALS AND METHODS: From May 1991 through June 2016, 53 patients were diagnosed retrospectively as having NMIBC with variant histology. Among these patients, 47 NMIBC patients with squamous differentiation or glandular differentiation were analyzed for this study. The median follow-up interval from diagnosis of NMIBC with variant histology was 28.9 months (1.5-168.8). RESULTS: Of these patients, 38 (80.9%) and 9 (19.1%) were diagnosed as having glandular differentiation and squamous differentiation, respectively. Radical cystectomy was conducted for six (12.8%) immediately after the diagnosis of NMIBC with variant histology. Of the 41 patients with bladder preservation, 20 (48.8%), 3 (7.3%), 3 (7.3%) and 15 (36.6%) underwent BCG, THP, MMC and no additional treatment, respectively. There were significant differences between BCG and other treatments or no additional treatment for recurrence (P = 0.034), progression (P = 0.004) and cancer-specific survival (P = 0.014). CONCLUSION: Overall, our results show that intravesical BCG instillation for variant histology in NMIBC leads to a better prognosis with regard to progression and cause-specific survival than other intravesical treatments or no additional treatment. BCG treatment may also have a clinical benefit for variant histology in non-muscle invasive bladder cancer patients.	bladder
Finasteride does not prevent bladder cancer: A secondary analysis of the Medical Therapy for Prostatic Symptoms Study.	BACKGROUND: Preclinical models have demonstrated that androgen receptor modulation can influence bladder carcinogenesis with an inverse association observed between serum androgen levels and bladder cancer (BC) incidence. It is still unclear whether 5α-reductase inhibitors, by preventing the conversion of testosterone to dihydrotestosterone, have a similar effect. This study aims to evaluate whether dihydrotestosterone-mediated androgen activity has an impact on BC incidence in a cohort of men included in a clinical trial of finasteride vs. placebo with rigorous compliance monitoring. METHODS: A secondary analysis was performed on all patients enrolled in the Medical Therapy for Prostatic Symptoms (MTOPS) Study and included in the biopsy substudy. Men were stratified into groups based on receiving finasteride and the incidence of BC compared between the groups. RESULTS: After exclusions for poor finasteride compliance (n = 338) and missing serum hormone results (n = 9), 2,700 men were eligible for analysis. In total, 0.8% (n = 18) of the cohort was diagnosed with BC during the trial period. There was no difference in the incidence of BC between men who received finasteride and those who did not (0.74% [n = 9] vs. 0.61% [n = 9], P = 0.67). Neither serum testosterone levels, prostate cancer diagnosis nor urinary bother (measured by International Prostate Symptom Score) demonstrated an association with BC diagnosis. These relationships were consistent in the subgroup of men in the biopsy substudy. CONCLUSION: There was no observable relationship between decreased dihydrotestosterone levels and BC diagnosis.	bladder
[Value of European Organisation for Research and Treatment of Cancer score system for predication of immediate postoperative intravesical instillation of pirarubicin after transurethral resection of non-muscle invasive bladder cancer].	Objective: To assess value of immediate postoperative intravesical instillation of pirarubicin after transurethral resection (TURBT)of non-muscle invasive bladder cancer. Methods: 484 patients diagnosed with non-muscle-invasive bladder cancer admitted to the Second Affiliated Hospital of Kunming Medical University were divided into two groups after transurethral resection of bladder tumor. 285 patients received postoperative intravesical instillation of pirarubicin within 6 hours after the surgery, 199 patients received first instillation of pirarubicin at 10 days after the surgery, after that, all the patients received routine bladder perfusion chemotherapy. Patients who received intravesical instillation of pirarubicin within 6 hours were defined as immediate intravesical instillation group and the other patients as the control group. Based on the European Organisation for Research and Treatment of Cancer risk tables, scores of recurrence and progression of patients were calculated and then stratified into risk groups accordingly. Recurrence and progression rates of the immediate intravesical instillation group were analyzed and then compared with the corresponding reference of the risk tables. Results: The 1-year and 5-year recurrence rate of patients with EORTC table scoring 0 in the immediate intravesical instillation group were significantly lower than that of the EORTC reference group (5.3% and 14.0% vs 15.0% and 31.0%, P<0.05). 1-year recurrence free rate between the immediate intravesical instillation group and the control group in patients scoring 1-4 was significantly different (81.3% vs 76.7%, P=0.014). However, 1-year recurrence free rate of the immediate intravesical instillation group was comparable with that of the control group in patients scoring 5-9, 10-17(P>0.05), which is quite close to the EORTC reference. The probability rates of 1-year and 5-year progression of the 285 patients who received immediate intravesical instillation group did not show significant difference with the EORTC reference. On multivariate analysis, previous recurrence, tumor grade G2-3, tumor multiplicity, delay of immediate intravesical instillation were independent risk factors of recurrence(P<0.05). Conclusions: With the help of EORTC recurrence risk table stratifying the patients into different risk groups, our study showed that delay of immediate postoperative intravesical instillation of chemotherapy after TURBT was an independent risk factor of post-surgery recurrence of tumor. Moreover, patients with EORTC scoring 1-4 might obtain greatest benefits.	bladder
